' vIn the use of. fan-fold packs of manifolding sheets with typewriters it.:has beendiflicult in 5 the past toiprevent fanning of the sheets. and

, web support to typewriters ofvarioussizes "or to preserve prior alignment with. the'typ'ewriter platen, owing. to the inadequacy of supporting devicespreviously commercially available. Al-

thoughv attempts have .-.been made to, providemanifolding web supports supposedtomaintain rectilinear alignment of the platenand the web support, despite the movementspf. the platen,

yet hasbeen found. that in every case theadvantages obtained were overbalanced in*impor-- tanee by thedifiiculties encountered andthe. dis-l advantagesmade manifest; Onemajor difliculty.

with'jprior devices has been that the load of the paper .web support, has been wholly. or in part carried by the typewriter carriage ;with a 'conse:-. querit substantiallyiinevitable retardation of the free movement of the platen and carriage. It is among the objects of this inventionto obvi ate the. difiiculties of prior constructionswof web supports; ,to provide improved means for. securing lateral movementof'the'web support in syne chronism with the movement of the typewriter carriage; to provide a driving arm for engagementwith a typewriter carriage and a websup:

port which "is completely operable regardless of therelative elevations of the web support and typewriter carriage and regardless of the vertical shifting of the carriage; to provide .animproved web support; topro-vide a novelclamp devicefor positioning a web support at a desired point; to provide a web support arrangedfo'r operable association with and disasscciation fromga typewriter in. a 'small time interval; toprovide'a web s'upport with a typewriter actuated arm with means for securing lateral adjustment of the" typewriter arm'to allow for application otl'the widths; tdprovidan'efi'icient simple web sup: port at a minimum of cost; and many other ob"- j'ects and. advantages as will, become more'a'pparent as the description proceeds. t

The projection 21 may be of any desired'sizeor contour in cross section,,.but is preferably formed as a channel having depending substantially radial ribs 28 whichterminate beyond the edge of the box 24 or bed 25 in a clamp 30 either cast or formedrigidly with the ribs 28 or attachedthereto any desired manner."

An arm 34 is slidably mounted -in the bore 3| and extends between the ribs-Z8 of the projection 27 toward the axis of theflangeZS.

To this end f it a is' desirable. that a permanent attachment be made 'to the typewriter suitable for guiding directing actuation of the 1 web support during-(their operative associationfbut} so arranged as to permitquick-disaSsociatioh of the- @Web support andthereafter the continued operation of. the typewriter without reduced: efficiency ldespite the j presence {of the permanent attachment."{Although such attachment may take-various iorms according-to the structural limitations off the typewriters with which it may be "associated; such devic'ei is disclosed in- Figs.

"The clips' engage in: peripheral grooves; as "29 in the -re sp ecti ve d t n jj Q -J ,w 5 l In the i preferredTorm of thfinve'ntion a tele scoping arm is provided edriiprismgia hollow tubular telescope element 42 jpivotally connected I bythe bearing portion to the cylindrical end 38 'of the'typewriter attachmenh' The complementary portio'nfofthe' telescoping arm comprises a 'rod, bar or tube 44, pivotally mounted by means-oi the-bearing iii to the reduced end 3.5

of the'adjustable arm 34' and having telescoping sliding engagement within tube 42. It is preferred that there be appreciable overlapping of the-tube 42 upon the rod or tube 44 so as to afford adequate guiding engagement. As shown in Fig. the rod .44 may have sliding engagementthrough a nipple or collar l9, made of suchvmaterial forinstance, as fiber, it sound insulation {is 'required, ..or which-may be made of metal, and. which takes half of the lateral stresses incident to movement of the typewriter carriage. The other half of the stress may be carried by 'a' plug 9,-of similar material, mounted onlthe endof rod 44. This modified arrangement may be substituted for the elongated bush- 5 ing 8,' shown in'Fig. 1. The important feature being thatthere be clearance in either telescoping form to' permit 'free axial movement.

Inthe other form of guiding arm the bearing 46"rotatably mounted onthe typewriter attachall; will'be understood that sometypes of'typewriters change the case byverticallyjshi'fting the platen. With either of 'the 'formsof arm disclosed herein such vertical' shifting will be almosti'completely absorbed int the bearings of the ends of the arms. i :Thisjis because the bearings must have suflicient clearance to move free- 1y when desired, and thisclearance maye'asily be such asito compensate for the very slight movement longitudinally occasioned by such case shifting If-thisvertical movement is exaggerated in some particular typewriter then? the telescoping or bending arms will'absorb-the longitudinal movement of the vertical shift;' Similarly any deviation in levels of the typewriter carriage and the web support suchl'as mayoccur due todifferentl types of desks 'withwhich the two are asisociated is immediatelycompensated for by the pivotalconnection of either arm at each end thereofyin connection 'withits elongation factor incident to t'elescopin'g' or folding. Then again, with the mounting for the web support disclosed herein oscillating on 'aswin'gin'g arm, there is longitudinal relative movement of the carriage and the web support, due tothe arcuate path of the .web supportijThis is compensated for by the telescoping 'or bending of either arm which may be used. Thus although the synchronized molvement of-gthe typewriter carriage and web support is in a,horizontal plane, it will be observed. that relative. movement of the carriage and web support may take place in three perpendicular. planes, of which one possible relative movement (in the horizontal plane) is precluded by the drivingengageme'nt of the arms, but'that the.,other two maytake place, simultaneously without jac lverse" v effect] a gina, rectilinear alignm'ent of the web'support andplatenor carriage. The alignment of the web support 24 with the typewriter platen is V a'jsimple and easy accomplishment. It is a feature of inenventionmatinee hi: :4

- has a movable dividing panel capable of instant adjustment to form a lateral 'guide for-one side nection including an arm extending between of a fan-fold pack with the side of the box forming the complementary parallel guide. To this I end the panel 52, of smaller, length than the side of the box, is provided with friction spring plates 53, which as shown in Fig. 2 in full lines, engage the ends of the box 24 when it is to be adjusted so that the panel 52 is not parallel with the sides of the box. Swinging movement to parallelism, causes the plates to be flexed and frictionally retain the given'guiding position.

It may be noted that variations in size of typewriter carriage may be compensated for by movement of the arm 34 relative to the axis of the support or of the points to be aligned. The assembly provides a certain, positive, quiet actuator to cause the web support to swing about the pivot formed by pivot 20, to maintain the bodily alignment of the typewriter carriage andweb support and simultaneously to cause the web support and swinging arm 2| to have relative movement such as to contribute toward the rectilinear alignment 1 of the support and the typewriter carriage.

Clearly the driving arm disclosed may be associated with other forms of web supports, such as those traveling on a track, although the track v has many disadvantages not attaching to the invention disclosed herein.
